Gene Variant Descriptions | PTEN G20E lies within the phosphatase tensin-type domain of the Pten protein (UniProt.org). G20E retains some, if not all, phosphatase activity compared to wild-type Pten (PMID: 10866302, PMID: 25263454, PMID: 17213812), however, G20E results in reduced membrane localization of the Pten protein due to impaired binding with membrane lipids, and subsequently, is unable to prevent Akt signaling, cell proliferation (PMID: 17213812), and cell migration and therefore, confers a loss of function to the Pten protein (PMID: 25263454). |
